SDelete vs. Standard Delete: Securely Erasing Sensitive Data

SDelete (Secure Delete) is an official, free command-line utility from Microsoft’s Sysinternals suite designed to permanently sanitize and wipe data so it cannot be recovered by data recovery tools.

Unlike standard Windows deletion, which only removes the file pointer and marks the space as available, SDelete physically overwrites the target disk sectors with random data patterns. This complies with strict data destruction standards like the U.S. Department of Defense standard DoD 5220.22-M. Setup and Installation

Because SDelete is a portable command-line tool, it does not have a traditional installer.
